Given numbers are 623, 217, 509, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(623, 217) = 19313
GCD(623, 217) = ( 623 x 217 ) / 19313
= 623 / 217
= 623
Step2:
LCM(7, 509) = 3563
GCD(7, 509) = ( 7 x 509 ) / 3563
= 7 / 509
= 7
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 623, 217, 509, 905 is 1
